An apparatus and method for engaging a mounting panel of a computer device includes a bracket, as well as a lever and slider mechanism connected to the bracket. The lever and slider mechanism includes a base, a wedge slider, a lever, a geared bar, and a biasing element. The base is connected to the bracket. The wedge slider is connected to the bracket and disposed immediately below the base. Rotating the lever from a first position to a second position causes a gear to engage the geared bar, causing the geared bar to move vertically. The rotating allows movement along the contact between an angled end of the geared bar and a wedged end protrusion of the wedge slider such that the biasing element pushes the wedge slider away from the bracket and allows the wedge slider to engage an opening in a mounting panel.
